As the core hardware component linking smart buildings with smart city ecosystems, intelligent building facades leverage technologies including sensor sensing, smart control systems, IoT, and artificial intelligence to achieve dynamic adjustment, environmental adaptation, energy efficiency, and data interoperability—serving as a pivotal unit connecting individual structures with urban smart operation systems. This paper examines smart city application scenarios to define the core concepts, characteristics, and urban value of intelligent building facades, establishing a design framework encompassing four strategic dimensions: comprehensive perception, low-carbon efficiency, urban planning integration, and safety-oriented design. It systematically analyzes technical challenges in implementation—including integration barriers, cost control, design standardization, and durability stability—and proposes targeted optimization solutions along with scalable deployment pathways, providing theoretical insights and practical support for innovative design, technological advancement, and large-scale adoption of intelligent building facade solutions in smart city environments.展开更多

The backward problem in CAPD is to search for the appropriate structure or composition of the product with desired property, which is an optimization problem. In this paper, a global optimization method of using the a BB algorithm to solve the backward problem is presented. In particular, a convex lower bounding function is constructed for the objective function formulated with BP-NN model, and the calculation of the key parameter a is implemented by recurring to the interval Hessian matrix of the objective function. Two case studies involving the design of dopamine β-hydroxylase (DβH) inhibitors and linear low density polyethylene (LLDPE) nano composites are investigated using the proposed method.展开更多

To sustain in the market on the move towards sustainability and meet the demands, companies need to re-examine their footprints and incorporate green practices in their products and organization. Using eco-friendly material & processes is one of the remedies to come up with this, and bamboo is one of the most versatile, green and renewable natural resources on planet earth. Traditionally bamboo has been exploited to a large extent but cutting-edge options available for bamboo are still limited and have a scope of indulging fully in the lifestyle of people in India. The global market size of bamboo was valued at UED 53.28 billion in 2020, and it is expected to grow at compound annual growth rate of 5.7% from 2022 to 2028. There is increasing demand for sustainable construction, and furniture and handicraft products also have considerable weightage. Manny brands and craft clusters of bamboo are realizing and promoting this green quotient of bamboo to the market to attract the eco-conscious audience and trying to cope up with the advancement of sustainability, like certifications of being a green organisation. Despite the exceptional qualities of bamboo, it is considered as a marginalized material due to low production rate, high competition with the non-eco-friendly or cheaper alternatives, aesthetics and marketing gaps. There is a gap between willingness to purchase and an actual purchase when it comes to the sustainable products and marketing plays a major role in conversions. The main purpose of the research is to study and understand the product, craft, design, production processes and marketing practices of bamboo lifestyle products and how conscious consumption patterns influence the bamboo products and the industry in relevance to the sustainability. Exploratory research method was applied with the literature survey and reviewing of the research papers from the peer reviewed journals. They were classified and reviewed based on the areas relevant to the bamboo products. The research outcome revealed the research gaps and the results were discussed and presented with the perspectives of product design, conscious consumption and marketing strategies in relevant to the sustainability of bamboo lifestyle products.展开更多

Table-top Lampshades direct the rays of light to make sight easier for reading whereas bedside lampshades provide romantic illumination and beautification in bedrooms. This art studio research sought to examine lampshades on Ghanaian market;their qualities, significance, shortcomings, etc. as the basis to design and produce inventive lampshades for private and public use. The study was conducted at an art studio condition using Practice-based research design method. Findings show that lampshades serve functional and aesthetic significance in public dwellings and the hospitality industry. Nonetheless, available lampshades on the Ghanaian market lack the multifunctional property as well as a local touch which arguably makes them misfit in Ghanaian context in terms of usage. The innovative results of the studio-produced lampshades revealed the possibility of creating symbolic and multifunctional lampshades which suit specific space and tradition. The study recommends the adoption of such innovative design approach in the creation of interior design and decoration artefacts for residential and public edifices.展开更多

If this feature is applied to product design, in addition to emphasizing functional orientation, this traditional arts integration with the new media, will give users a different visual inspire. This thesis is mainly in view of the importance of hollow out art in Chinese cultural heritage, and the 3D hollow out production craft has gradually lost. Therefore, the Delaunay triangle is constructed based on the Convex Hull interpolation algorithm, and the Voronoi Diagram feature is constructed based on the Divide and Conquer algorithm. And with Rhino modeling software as the main body, combined with the application of the parametric plug-in design program (GH), the 3D models of the parametric creative hollow pen holder and the parametric creative hollow lampshade were respectively completed. The traditional craftsmanship is integrated into the modern manufacturing process with innovative techniques, and the Chinese cultural spirit and beauty of nature are successfully connected.展开更多

摘要Against the dual backdrop of comprehensive smart city development, refined urban spatial management, and the deep implementation of the dual-carbon strategy, traditional fixed architectural facade products exhibit limitations such as single functionality, poor environmental adaptability, high energy consumption, and lack of intelligence, making them inadequate for meeting the dynamic, low-carbon, and human-centric demands of smart cities. As the core hardware component linking smart buildings with smart city ecosystems, intelligent building facades leverage technologies including sensor sensing, smart control systems, IoT, and artificial intelligence to achieve dynamic adjustment, environmental adaptation, energy efficiency, and data interoperability—serving as a pivotal unit connecting individual structures with urban smart operation systems. This paper examines smart city application scenarios to define the core concepts, characteristics, and urban value of intelligent building facades, establishing a design framework encompassing four strategic dimensions: comprehensive perception, low-carbon efficiency, urban planning integration, and safety-oriented design. It systematically analyzes technical challenges in implementation—including integration barriers, cost control, design standardization, and durability stability—and proposes targeted optimization solutions along with scalable deployment pathways, providing theoretical insights and practical support for innovative design, technological advancement, and large-scale adoption of intelligent building facade solutions in smart city environments.

Judging from its impact, the application of this industrial product design method can further enhance the practicability and appreciation of industrial products. Under the background of rapid changes in social concepts, many designers have fully realized the advantages of this design method and effectively applied it. Judging from its application effect, the aesthetic features are obvious. In the whole industrial product design work, the minimalist style also affects the development of product design work because of its unique characteristics. Therefore, it can be seen that the study of industrial product design under the minimalist style has positive social significance.
摘要Chinese culture has been continuously developing for 5000 years of historical development.Its traditional culture has had an impact on social development,and this traditional culture is rooted in the development of the society.The traditional Chinese culture also has certain significance for the design of modem cultural and creative works,which does not only inject vitality for cultural and creative products,but it also enhances the artistry of cultural and creative products.Therefore,based on this,this paper expounds the concept of traditional Chinese culture with cultural and creative products,analyzes the value of traditional culture in cultural and creative products,and explores how to refine and draw lessons from traditional Chinese cultural elements in the process of cultural and creative product design.

摘要The creation of hollow out art includes a variety of materials, techniques and categories, its content mostly emphasizes the ancient philosophy performance of the alternation of virtual and real, and Yin-Yang depends on the essence of Chinese culture deduction. If this feature is applied to product design, in addition to emphasizing functional orientation, this traditional arts integration with the new media, will give users a different visual inspire. This thesis is mainly in view of the importance of hollow out art in Chinese cultural heritage, and the 3D hollow out production craft has gradually lost. Therefore, the Delaunay triangle is constructed based on the Convex Hull interpolation algorithm, and the Voronoi Diagram feature is constructed based on the Divide and Conquer algorithm. And with Rhino modeling software as the main body, combined with the application of the parametric plug-in design program (GH), the 3D models of the parametric creative hollow pen holder and the parametric creative hollow lampshade were respectively completed. The traditional craftsmanship is integrated into the modern manufacturing process with innovative techniques, and the Chinese cultural spirit and beauty of nature are successfully connected.
